Why do you have mobis on warwick?

If you are just absolutely getting stomped then why do you still have your mobi boots? I don't understand, when you're behind as ww you're almost useless so why build something that makes you even slower in teamfights.

I told my teammate to get mercs and he responds with "why mercs?" and then the support tells me to hush because I don't know how to play warwick.

Coming from an annie that also is wearing mobi and died 16 times.

Linear build patterns in bronze frustrate me. "I usuall build like this so it's always the right way to go" mentality.
